Anti-Counterfeit Product System Using Blockchain Technology

Fake Products is a serious issue, as in today’s world we can’t really distinguish between real and fake product. And some people make these fake products just to make some profit without thinking about its impact on user and also affects company’s name, profit and sales. Blockchain technology can be used to detect whether the product is real or fake and assure user about the authenticity of the product. Blockchain is a trending technology and lot of applications are using this technology. Blockchain technology is the technology where information is stored in the form of blocks in many databases which is connected with the chains and it doesn’t require any third-party users for permission. Benefits of blockchain is that it is immutable and secure. It is decentralized and distributed. We can use Quick Response [1] (QR) code or an encrypted unique code which is a very efficient technique to detect fake product. When the QR code is scanned or the unique code in entered, it will redirect us to the blockchain containing the information of the product and provides us the details of the manufacturer and information of owner to make decision easy for buyer if they are looking to buy the product.

DESIGN OF AN AUTONOMOUS SOLAR ROTARY COMPOSTER WITH SHREDDER SHAFT

Composting is the most efficient technique for managing household organic waste; it is the most widely used technique in the world. To improve and accelerate the composting process and produce rich and stable compost, it is necessary to grind and shred organic waste into small pieces to facilitate the degradation of the material by microorganisms. This paper presents the design, sizing, and modeling of a new self-contained, solar-powered, rotating composter with a shredding shaft. This shredding shaft rotates at 350 rpm and must run for 5 minutes before starting the composting process. This innovative machine shreds and composts organic household waste in situ to produce stable, mature compost suitable for agricultural use, providing an effective solution for managing and recovering organic household waste.
